I Specification of Letters Patent. Patented Jan. 1917.

' Application filed December 2, 1915. Serial No. 64,760.

To all whom z't-may' concern: I I 7 Be it known that I, EPHREM FiiLix VALI- unT, a subject of the King'of Great Britain, and reslding at 23 Atwater avenue, in. the city of Montreal, in'theProvince of Quebec,

Canada, have invented certain new and use-l ful Improvements in Winding-Indicators? and I do hereby declare that the'following is a full, clear, andexact description ofv the same. I.

The invention relates to anew and useful improvement in a winding indicator, and it is the primary object of the' invention to provide a novel device of this character, wherein the numerals on the dial will, automatically disappear at a 'determined'time,

thereby indicating that it is necessary to rewind the motor of the watch.- I I It is also the object of "the invention'to provide a novel device of this character which will be simple in construction, efii- 'cient and advantageous in practice and inexpensive to manufacture.

With the above objects in view, the .invention consists in the detailsof construction and in thenovel arrangement and combination of parts to be hereinafter. more particularly referred to.

In describing the invention n deta1l,,ref'- erenqe will be had to the accompanying;

. drawings forming part. of this specification,

wherein like characters of reference denote corresponding-parts in the several views, in

which Figure 1 is a front elevation of a watch illustrating the special dial apphed thereto,

the numerals being visible. Fig. 2 is a rear elevation of the watch, the movements: of the watch having been removed and the invention applied onthe inner face of the dial. Fig. 3' is a front elevation of the watch, illustrating the special, dial apphed thereto, the numerals being invisible, thus indicating that the watchmust be rewound. Fig. 4 is across section view on line A- A in Fig. 2. Fig. 5 is an enlarged detail view of the spring-held operating lever. Fig. 6

is an enlarged view of the spring-held releasing lever. Fig. 7 is an enlarged view showing the detent and I .its allied parts. clearly and without'the watch case in front of the parts.

Like numerals of reference indicate corresponding parts in each figure.

; In the drawings, 1 denotes the-casing of anordinary: watch and-2 is the dial, dis posed wlthln' its circumference, having a plurality of circu1ar openings 3, through I.

slide-way 6 formed in the plate7. It may be here mentioned that in swinging the circular band 5,the numerals will disappear under the dial 2 asillustrated in Fig. 3,

thereby indicating thatthe watch mustbe rewound. The plate 7- is provided with elongated slots 8, 9 and 10,'which abut within the slide-way or channel 6; On the inner face of said plate .7 is suitably mounted the gear 11, which'is provided with a pin12, secured withln its circumference, said pin 12 being adapted to disengage the releasing pawl 13, which is pivoted to asuitable bracket 14 and held by the" spring 15 in engagement with the "pin 16. Said pin 16 is p secured to the inner side of the circular band 5 and projects through theopening 9 provided in the plate 7. The said pawl 13 is provided at its free end with a notch 17,

which is adapted to engage a corresponding projection onthe pin 16.

18 is a tension spring pivoted. to the pivot 19 atone end and at the other end to the pin 20, which is secured on the inner face ofthe circular band '5 and projects through the slot .oropening 9.

21 is the operating pawl pivotally-secured on the pivot 22, which in turn is secured on the circular band 5 rand-projects through -theopening 10in the plate 7, said pawl 21 being provided at one end with a hook 23,"

which .is adapted to engage the gear 24, mounted onthe ordinary shaft of the watch spring. At the otherend, the saidpawl 21 is provided with anoutwardly projecting point 26, which is adapted tocontact with the flat spring 27. and cause the hook 23 to engage the teeth of the gear 24.

28 is a flat spring suitably secured on the plate 7 and adapted topre'ss the pawl 21 out of engagement with the gear 24:.

29 is a pinion mounted, on the minute 7 wheel and adapted to rotate the gear or hour wheel 30. Said hour wheel30 is so arranged that it will engage the gear 11 and causelsame to rotate. I

When the watch is in operationpthe minute wheel 29 and thehour wheel30 Will gear 11, to engage the pawl 13 and: cause it to release the pin 16. The spring 18 which is connected at one end to the pivot 19 on the plate 7 and at the other end to the pin 20 on the circular band" 5 will cause said circular band to rotate and thereby push the numerals on the said circular band out of vision, and, therefore, will have the effect to advise or signal that the watch must be the gear 11 by means of the hour wheel is that, should the watchbecome out of order, or should the time be corrected, it will automatically at the same time correct the time for releasing the pawl. 13. Immediately on winding the watch, the shaft 25 will cause the gear24= to rotate and it will thereby pull the pawl 21 which is in engagement with the said gear 24 when the numerals are out of vision, also rotating the circular band 5, which will retake its primary position, the releasing pawl being immediately pressed down by the spring 1 5, will engage the pin 16 and lock the circular band in its normal or primary position. By providing for the releasing of the circular band 5 considerably before the watch is completely unwound any variation of the speedfor being allowed to run while the tension ofthe spring is very weak is prevented, and byproviding for the immediate action of the circular band 5 to come into'its normal place as the watch is being wound up, will prevent any overexertion of the spring, and, therefore, eliminate trouble which may arise fromunnecessary tension onthe spring.

In the invention herewith described, the numerals on the band 5 will become invisible regularly, at a' specified time, no matter if the watch is rewound or not.

The preferred form is herewith described and it is thought that the description will be.

found to be sufliciently clear.
